Could This Visitor From Another Star System Be Alien Technology? SETI Investigates
Researchers found no radio technosignatures and ruled out transmitters stronger than about 10 to 110 watts near the interstellar object, the paper said.

3I/ATLAS Mystery Explained: California Scientists Hunt for Alien Tech on Rare Interstellar Object
Scientists in California have completed one of the first dedicated searches for signs of alien technology on 3I/ATLAS, the latest known object to enter the solar system from interstellar space, finding no evidence of artificial radio signals. A recent #SETILive conversation between @allplanets and planetary scientist Dr. Cecilia Tubiana (INAF) explored ESA’s Juice observations of the interstellar comet 3I/ATLAS as it traversed the inner Solar Sy…
California scientists scanned 3I/ATLAS for alien tech, and found only Earth-based noise
A newly spotted interstellar visitor just got an unusually close listen from California scientists — in a search for signs of technology. The verdict was less science fiction than some might have hoped: no alien beacon, just a great deal of radio noise from Earth. Still, for researchers who study the rare objects that pass through our solar system from beyond it, that outcome is far from meaningless. What happened? When astronomers identified 3I…
Could This Visitor From Another Star System Be Alien Technology? SETI Investigates
A rare visitor from another star system prompted SETI to hunt for alien technology, but the mysterious object appears to be a natural cosmic traveler after all. Scientists have completed a search for signs of alien technology from 3I/ATLAS, the third known interstellar object ever observed passing through our Solar System. Using the Allen Telescope [...]
The interstellar object 3I/ATLAS, discovered in July 2025, was the subject of an investigation by the SETI Institute to identify possible signs of extraterrestrial technology. The research, conducted using the Allen Telescope Array (ATA), found no evidence to support the hypothesis that the object was artificial. Description of object 3I/ATLAS: 3I/ATLAS is the third confirmed interstellar object to pass through the Solar System, after 1I/’Oumuam…
